We sell best bosch Injector Valve and top quality Common rail injector valve of Auto Parts.

Production common rail fuel systems are equipped with a closed-loop high pressure control-system that stabilizes the rail pressure within a relatively small margin to the nominal value specified by the electronic control unit for a given engine operating condition. The pump maintains the rail pressure by continuously delivering fuel to the common rail. This pressure is monitored by a pressure sensor and the difference between the nominal rail pressure value and the measured one is the input signal for the controller.
